First install the JDK version in your Linux box in any directory. I will install the JDK in /u01/app/oracle like I show you in the next screens:

chmod a+x jdk-6u-linux-i586.bin

./jdk-6u-linux-i586.bin

Install SQL Developer

Then install SQL Developer rpm using the next command:

rpm -Uhv sqldeveloper-2.1.1.64.45-1.noarch.rpm

Next, verify if the file jdk contains the JDK’s path. This file is located in $HOME/.sqldeveloper. If the JDK’s path that you installed previously isn’t registered in the jdk file, the first time that you launch the application, you should be prompted to provide the path.
